Lightspeed and before were from the "old" Bauer. Not just that, but as stated above, the Edge holder is not efficient and the top level players are going to change to anything that will give them a step up. This is why you're seeing guys moving to different steel, holders, skates, etc. CCM and True now have products that rival the edge in terms of functionality as well as being better in overall quality. This could obviously change as those are still relatively new, but unless Bauer changes the edge holder, it's going to be able to keep up with these new holders. People want choices. They don't want to be railroaded into equipment just because.
I'm not sure why Bauer wouldn't have wanted to work WITH Step, especially at the top end of their skate lines. I feel like this was a huge misstep (over the course of many missteps by Bauer) to achieve greater customer return purchases while offering some of the best steel in the market.
Bauer is also doing the same thing with the Easton tech they acquired. If you're following anything dealing with the new Flylite taper, they're already having issues with breakage on these sticks and many of the pro's that are "using" them are actually using something else with the flylite graphics, usually ADV vapors. We as consumers need to voice our concerns so they start actually providing decent products again.
